Stablecoins are just tokenized versions of exisiting currencies. Instead of settling through the current financial system which takes days for a global transaction you settle on a blockchain within seconds or minutes. These stablecoins will probably be issued on existing global blockchains like Ethereum so they might all be interoperable within a single system just like SWIFT currently supports multiple currencies.
